[0009]

Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the hanging device 1 of the present embodiment includes a substantially rectangular substrate 2, and a long groove-shaped insertion groove 2 extending in the longitudinal direction of the substrate 2 at one end of the substrate 2.
a is formed. A substantially U-shaped reinforcing angle 2b is fixed to the peripheral edge on the back surface side of the substrate 2 along three sides except one side where the entrance of the insertion groove 2a is located.

On the other end of the substrate 2, a column 3 is erected perpendicular to the substrate 2. A stopper plate 4 (stopper portion) is fitted and fixed by a hole 4a slightly below the upper end of the column 3. A holding plate 5 is arranged between the substrate 2 and the stopper plate 4 in parallel with the substrate 2. The holding plate 5 is movably and rotatably fitted to the column 3 through a hole 5 a (see FIG. 2) and is urged toward the substrate 2 by a coil spring 6 contracted between the holding plate 5 and the stopper plate 4. I have.

The holding plate 5 is formed with a circular insertion hole 5b corresponding to the depth of the insertion groove 2a of the substrate 2, and one end of the holding plate 5 corresponds to the entrance of the insertion groove 2a. Thus, an engagement protrusion 5c is provided, and the engagement protrusion 5c extends vertically downward in parallel with the column 3.

A substantially arcuate shackle 7 is rotatably connected to the upper end of the column 3. That is, the support 3
A horizontal hole 3a is drilled at the upper end of the
Holes 7a are formed at both ends of the shackle 7, and holes 3a are formed.
The support 3 and the shackle 7 are connected by a rivet 8 that penetrates a and 7a. The shackle 7 is connected to a lower end of a rope 9 of a lifting device such as a trolley crane (not shown).

When the outer wall panel 11 is lifted by using the above-described hanging tool 1, as shown in FIG.
And a nut 15 is screwed near the upper end of the mounting bolt 13. First, a sufficient gap is provided between the substrate 2 and the holding plate 5 by pushing up the holding plate 5 against the urging force of the coil spring 6, and in this state, the board 2 is moved to the outer wall panel 11. Then, the mounting bolt 13 of the outer wall panel 11 is inserted to the depth of the insertion groove 2a by moving the mounting bolt 13 in the horizontal direction to the side approaching the vertical direction, whereby the mounting bolt 13 is inserted vertically in the insertion groove 2a. If the holding plate 5 is rotated in a direction substantially perpendicular to the substrate 2 when the mounting bolt 13 is inserted into the insertion groove 2a, interference between the mounting bolt 13 and the engagement protrusion 5c can be avoided. It can be easily inserted.

Thereafter, the pressing plate 5 is moved downward by the urging force of the coil spring 6 while aligning the insertion hole 5b of the pressing plate 5 with the mounting bolt 13, and as shown in FIG.
The mounting bolt 13 is inserted through the insertion hole 5b, and the engagement protrusion 5c is engaged with the entrance of the insertion groove 2a. Thus, the nut 15 is sandwiched between the substrate 2 and the holding plate 5 by the urging force of the coil spring 6, and the hanging tool 1 is connected to the mounting bolt 13.

In this coupled state, the lifting device such as the trolley crane is driven to lift the outer wall panel 11 to the position of the beam, and then the lifting tool 1 is separated from the mounting bolt 13. In this case, contrary to the above, the holding plate 5 is
The mounting bolt 13 is detached from the insertion hole 5b, the engagement protrusion 5c is detached from the insertion groove 2a, and the board 2 is moved in a direction away from the outer wall panel 11 to be attached from the insertion groove 2a. The bolt 13 may be removed.

In the above embodiment, the engagement protrusion 5c is engaged with the entrance of the insertion groove 2a. However, the engagement groove in which the engagement protrusion 5c engages with the substrate 2 separately from the insertion groove 2a. (Engaged portion) may be provided. In this case, the position of the engagement groove or the like may be, for example, on the side opposite to the insertion groove 2a with the support 3 interposed therebetween. Further, it is possible to provide an engagement protrusion on the substrate 2 and an engagement groove or the like on the holding plate 5.
The provision of the engaged portion (the insertion groove 2a) and the engagement projection has an advantage that the rotation between the substrate 2 and the holding plate 5 is reliably prevented, and the nut 15 can be securely clamped. Since the mounting bolt 13 itself has the function of preventing rotation, the basic function of the hanging tool 1 is not impaired even if the engaging projection is omitted.

The outer wall panel that can be lifted by the hanging device 1 of the present invention is not limited to the above-described outer wall panel 11. For example, as shown in FIG. The outer wall panel 11a in which the mounting bolts 13 are vertically mounted via the L-shaped fastener 10 may be used. In other words, any outer wall panel in which the vertical mounting bolts are provided at the upper end on the back side may be used. It may be something.

[0018]

As described above, according to the first aspect of the present invention,
The hanging device is a hanging device vertically attached to the upper end on the back side of the outer wall panel and detachably connected to a mounting bolt screwed with a nut to lift the outer wall panel, and has an insertion groove at one end. A substrate provided with a support, a support erected on the substrate, a stopper provided on the support with a predetermined gap between the substrate, and a stopper between the substrate and the stopper. A holding plate movably supported by the column and provided with an insertion hole corresponding to the insertion groove, and a biasing unit for biasing the holding plate toward the substrate;
In a state where the mounting bolt is inserted through the insertion groove and the insertion hole, the nut is sandwiched between the substrate and the holding plate to be connected to the mounting bolt.

Thus, when the outer wall panel is lifted, the nut on the mounting bolt is inserted into the insertion groove of the substrate and the insertion hole of the holding plate, and the nut on the mounting bolt is pressed against the substrate by the urging force of the urging means. Just by sandwiching in between, the hanging tool can be easily connected to the mounting bolt, and after lifting the outer wall panel, the holding plate is lifted against the urging force of the urging means, and By simply detaching the mounting bolt from the insertion groove, the mounting bolt and the hanging tool can be easily separated from each other, so that the work of lifting the outer wall panel can be easily performed.

According to a second aspect of the present invention, in the configuration of the first aspect, an engaged portion is provided on one of the substrate and the holding plate, and the other is engaged with the nut while the nut is clamped. Since the engaging projection is provided to engage with the portion, by engaging the engaging projection with the engaged portion, the rotation of the holding plate with respect to the substrate can be surely prevented. The nut is firmly clamped between the substrate and the holding plate, so that the mounting bolt can be more reliably supported by the hanging tool.

According to a third aspect of the present invention, in the construction of the second aspect, the engaging projection is provided on the pressing plate, and the engaged portion is an insertion groove of the substrate. It is no longer necessary to provide them independently, thereby simplifying the configuration.
